The reason behind Miley's lithe photo? A fan a.k.a. "smiler" gave them to her. While Madonna didn't have a fan to thank a fan for hers but she did say it was an unapologetic way of preparing for her 56th birthday.

Earlier this year, on January 29, Miley and Madonna performed and dirty danced together at the MTV Miley Cyrus Unplugged concert special.

At the time, Miley told the audience, "It sounds super-lame, but as a pop star it's pretty cool performing with Madonna . . . Today was one of those days that it was really easy to get out of bed, put on a bikini and sing with Madonna."
